           Summary: filters apply more and more times on each repaint
           Product: WebKit
           Version: 420+ (nightly)
          Platform: Macintosh
        OS/Version: Mac OS X 10.0
            Status: NEW
          Severity: normal
          Priority: P2
         Component: SVG
        AssignedTo: webkit-unassigned at opendarwin.org
        ReportedBy: mjs at apple.com


Filters appear to apply more and more times on each repaint. This is visible in
the effect of the filter, and the paint gets slower and slower each time.

Steps to reproduce:

1) Load LayoutTests/svg/custom/text-filter.svg
2) Open another (empty) tab
3) Switch back and forth between the tabs, for example using cmd-shift-[ and
cmd-shift=]

Results:

The text gets more blurry each time, and the paint takes longer each time.

Expected results:

The visual output should be the same each time and should not take any longer.
